Re: Centralized unit commitment and your concerns. A few things to think about. Here are a few options: 1) Have the ISO do it (you can also have "bid-zero" bilaterals if you want but the basic mechanism is the same). This effectively gives you PJM, New York, etc. 2) You can have the traded flowgates approach, with the flowgate rights needed to schedule. That way you get the right plants on in the right places, in theory at least. This might be interesting as a future development, but as we have previously agreed it is way too untested for us= e now. 3) You can have the transmission rights (e.g flow rights a la Alliance) be purely financial hedges (similar in some ways to FTRs), but you don't need the flow right to schedule a transaction. This is the way that a bunch of the RTOs seem to be going (e.g. Alliance). But this still leaves you needin= g a way to create that feasible schedule. You can get feasibility by RT through the LMP but my sense is that the RTO needs to make sure there is enough capacity ready so that reliability can be protected. The problem of the financial-only flowgate method in my book is that it doesn't meet one o= f the key characteristics of a workable market - e.g. it doesn't really solve the problem of congestion while there is time to do anything about it (e.g. bring more plants online other than a few CTs, hydros, etc.). The RTO will need some way to handle this problem, or else handle large volumes of MWh b= y OOM calls at its discretion. I don't think we like that. I was talking with some people about Alliance on Monday and they seem to have sort of lost track of the ball, at least in my book. They are now talking about an alternative method for dealing with day-ahead congestion. This would effectively take the form of the re-dispatch type process used i= n California. My view is that this sounds pretty clumsy, adds a lot of complication, and will be great fun for the big generators in Alliance. Under this system I want to be AEP - the 600 pound gorilla of the region. And it is still effectvely centralized - the ISO takes in inc/dec bids and broadcasts out prices, calculated by the OPF model. It has all of the elements of LMP, just done more than once. If I am a big intergrated generator/load utility with market power I can repeat the old games of creating congestion by my scheduling in a constrained area and then getting paid to unwind it. So I think we have some basic questions to address next week on the call. I just want to make sure we get an RTO model that can be made to work without too much duct tape and bailing wire. If we want to jump off the centralized unit commitment train we may need to go back and consider all of the economic angles quite carefully. I am generally sympathetic to the decentralized commitment idea but I also want to make sure we don't end up with a muddle.
